Review on 🐠 IceCap Dual Optical ATO: Advanced Auto Top Off Controller for Hassle-Free Aquarium Maintenance by Megan Holtz

I have this set of 20 long reefs (no swamp) in my shop and it works very well! Easy to set up and very sensitive. My salt level now stays constant. The mount and sensors are very small so they work well in a nano tank without a sump. My only issue with it was the pump when I first tried to use it. For some reason the impeller was not spinning. I disassembled and reassembled it and it's been working ever since. I've been building for a week and a half now. If anything changes I will update this review.
